FAQs on 100mm Fused Silica Wafer:

What are fused silica wafers used for?

Fused silica wafers are most commonly used to manufacture optical and semiconductor components like lenses, prisms, filters, photomasks, and microfluidic devices. They can withstand high temps.

What thickness options do you offer for 100mm fused silica wafers?

We offer standard thicknesses ranging from 0.5mm to 2.0mm. Thinner or thicker wafers can also be customized including ultra-thin 100mm fused silica down to 10 microns.

What surface roughness options are available?

Our standard 4″ fused silica wafers have surface roughness starting at <5Å Ra. We offer custom polished fused silica wafers with standard surface roughness starting at <5Å Ra and ranging to super polished <1Å Ra, tailored to your application needs.

Do you supply prime or reclaimed fused silica wafers?

We supply prime grade 100mm fused silica wafers only.

Can I order smaller quantities of 100mm fused silica wafers?

Minimum order quantity is one full cassette which has 25 wafers.

How long is the lead time for 4″ fused silica wafer orders?

Lead times for stock wafers are typically 1-2 days. Customized 100mm wafers generally require a 4-6 week manufacturing time depending on your specs.
